I was just reading through the owners manual and it says they "strongly recommend" 0W – 20 oil and do not recommend the use of other viscosities except for short-term use when 0W – 20 isn't available. Thicker oils will prolong warm-up time and reduce fuel economy. In the long run it puts extra pressure on the seals and gaskets as well. Not really a good idea to do. These modern engines have very tight tolerances .

I wouldn’t worry too much about running 5w30. Here is a example from Mitsubishi Singapore that specifies 5w40 as the recommended oil on Page 3 for all of the models they sell including the Mirage (Spacestar)

Recently purchased Parts Master #61356. 12 filters for $34 shipped. Same specs, distribution center, and manufacturing plant in Mexico as Wix #51356 oil filter. Also part of Affinia Motor Group same as WIX. Look at specs below. Good deal imo.

Exactly. It's all about cafe standards and regs in this country. It's pretty funny when the exact engine, not just Mitsubishi, calls for different oil in different countries.

I feel a 0w30 would be a good middle ground. Same start up as 0w20 but a more robust oil at opp. Temp. And when the 20 sheers down it will be like water. At least when a 30 sheers down it will still be at least a 20 or more.

i agree wholeheartedly. If it ever got below freezing here on the Southern Oregon Coast I’d run 0w30. The viscosity levels of 0w20 at 100C (212F) are shockingly low.
